BOOK-HOLDER.

SPECIFICATION forming part of Letters Patent No. 669,522, dated March 12, 1901.

Application filed July 10, 1900. $erial No. 23.140. (No model.)

To aZZ whom, it may concern:

Be it known that I, RIGGS P. HAOKWORTH, a citizen of the United States, residing at Ledbet-ter, in the county of Fayette and State of Texas, have invented certain new and useful Improvements in Book- Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to book-holders in general, and more particularly to that class designed to receive and hold a book or tablet in proper position for Writing thereon; and it has specific reference to means for holding a check-book or a post-office money-order book in such position that the blank portions may be readily filled in and the completed blank removed with ease and despatch.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in both Views, Figure 1 is a perspective View of the holder removed from a desk and holding a tablet of forms. Fig. 2 is a longitudinal section of the complete device, showing it in position set flush in the top of a desk.

Referring now to the drawings, the holder comprises a preferably rectangular casing including sides 5 and '6 and ends 7 and 8, the depth of the casing or box being somewhat greater than thethickness of the tablet to be held, as indicated in the drawings. The box or casin g has a false bottom 9, which directly receives and supports the tablet, and which false bottom is adapted for adjustment vertically of the box to raise and lower the tablet with respect thereto. In order to thus adjust the false bottom, plates 10 are provided,which plates have their inner ends broadened and perforated to receive screws 12, through the medium of which the plates are held to the false bottom.

The central portions of the plates are narrowed, as shown at 13, and these narrowed portions are slidably disposed in slots 14 in the ends of the box or casing, the protruding ends of the plates being also enlarged and having threaded perforations, which engage the threads of feed-screws 15, these plates being thus, in efiect, followers.

The feed-screws 15 are rotatably mounted with respect to the casing through the medium of upper outwardlyextendiug plates 16, which project from the upper edges of the ends of the casing and are perforated to form bearings for the feed-screws, which are engaged therewith. The lower ends of the feedscrews are rotatably mounted in outwardlyprojecting ears 17 on the ends of the casing and at the lower end thereof. The upper end of each of the feed-screws projects above its respective plate 16 and has a head 18 to facilitate rotation of the screw by the operator, it being thus seen that as the screws are moved in one direction the false bottom 9 will be moved upwardly and when the screws are rotated in an opposite direction the false bottom is fed downwardly, thus effecting a raising and lowering of the tablet supported by the false bottom.

The plates 16 are provided with perforations 20 to receive attaching-screws, by means of which the device is held in position, it being understood that the casing is set with its upper edge flush with the top of a desk or other support, and in order to limit the upward movement of the false bottom to a point to hold the tablet flush with the top of the desk a stop-plate 21 is pivoted at one end to the upper face of one of the plates 16 and is adapted for pivotal movement to lie above and transversely of the tablet on the false bottom, so that the feed-screws may be operated only sufficiently far to bring the tablet to the proper position. By moving the stopplate pivotally it may be swung from its operative position and the tablet may be removed.

It will be understood that in practice various modifications of the invention maybe made and that any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.

What is claimed is 1. A book or tablet holder, comprising a casing having slotted ends, a false bottom slidably mounted in the casing and adapted to receive and support a tablet or book, plates secured to the bot-tom and including narrowed portions engaging the slots in the ends of the casing, com bined bearing and attaching plates carried by the casing, ears upon the casing, and feed-screws rotatably mounted in the plates and ears and having threaded engagement with the projecting portions of the firstnamed plates to reciprocate the false bottom in the casing.

2. A book or tablet holder, comprising a casing having slotted ends, a false bottom slidably mounted in the casing and adapted to receive and support a book or tablet, plates connected to the bottom and slidably engaging the slots formed in the ends of the easing, the projecting ends of the plates having threaded perforations, combined bearing and attaching plates carried by the casing and adapted for engagement by attaching means to hold the casing upon a support, ears upon the casing, feed-screws engaging the threaded perforations of the first-named plates and rotatably mounted in the bearing-plates and in the ears,and a stop-plate pivotally mounted upon one of the attaching-plates, and adapted to lie in the path of upward movement of a tablet or book on the false bottom.

In testimony whereof I hereunto set my hand, this 7th day of May, 1900, in the presence of two witnesses.

RIGGS P. HACKWORTH.
